Overclock Voltage, Temps and ASUS Suite 3 Question

Hey Folks. Wondering if some OC'ing pros can give me some advice over here.

So here in the picture which I've posted along with this question, you can see the results from a 5 minute and 55 minute stress test. I have ran AIDA64 for 8 Hours and it was all gravy but this is just to give you an idea of what I'm on about here.

As you can see, at 100% load, my temps sit around the 60 mark, sometimes jumping to 70~ and even dropping to sub 50.

But this is where it gets weird. I'm using a Z170 Pro Gaming Aura. With this Mobo, I downloaded the Asus AI Suite 3. I never used it to do an OC though. I only OC'd through the BIOS / UEFI.

Thing is, I struggled to get 4.7 GHz Stable OC on my 6700k unless I upped the Core Voltage to 1.42v. Which seems damn high to me.

When I was doing stress tests with AI Suite installed, my temps would hit the high 70's, maybe even break 80+.

I've just uninstalled it, which was a pain in the butt in itself, and now when I look at the VID Voltage in HWMonitor, the voltage never went above 1.39v and mainly stayed around 1.35v.

I'd heard people around the "internet" say that AI Suite can over step the need of it's voltage and some others have said it can cause instability at lower Voltages.

I know this is probably hard to understand and I could've worded it better but is this a sign that ASUS' AI Suite is gimping our OC's and I can now safely reduce my core voltage that it's uninstalled?

And also, are these temps considered "good" for a 6700k OC'd to 4.7GHz. I've attached links which show temps at idle, load for 5 mins and load for 55 mins.

Cheers all, I appreciate any and all constructive feedback! :)


P.S - The cooler I'm using is a H100i in push/pull config, all Corsair SP120's. The PSU I'm using is a EVGA 850w P2 and I am using 2 braided cable extensions on the Graphics Card (8 Pin + 6 Pin) and 24 Pin extension for the Mobo.

Ignore VID, VID is what the processor request for voltage set by ASUS. Look at vcore readings and don't use HWmonitor, it's bugged to show the wrong voltage as shown in your screenshots.
Temperature looks good, as long you don't get over sustained 80c cpu core temperatures you should be fine.

When people mean AI suite overvolt, it's when you choose to allow the software to do the overclock for you in which it sets a higher voltage than necessary. Also when you're running AI suite in the background, it is using your cpu still even during stress test.

Hi Suztera, thanks for your reply.

So running 4.7GHz at 1.42v is more than healthy? I've assumed so and It's been running pretty great thus far.

And yeah the temps seem to go no higher than 74c and that's when it spikes. It settles around 62-64c for the majority of the time when at 100% cpu load.

Is it safe to go any higher, the general consensus I've heard is to not go above 1.45v on the CPU.

Once again, thanks :)

Sorry I forgot to ask also, PSU extension cables, specifically for the 24 pin mobo cable and the GPU (8 + 6 Pin), could these affect OC stability and force users to up there Voltage for better stability?

 
it depends how comfortable you feel. Some prefer to not past 1.35V whilst some are happy with 1.4v. Of course, using a higher voltage may potentially lower the lifespan of the cpu. Intel states the cpu is "safe" running up to 1.52v but most would still recommend you up to 1.35v/1.4V.
You can test without using the extension cables, it's unlikely if it is built to specification.

I bought them a while ago, 3 or so years now.

They are purely extensions, not custom braided cables. I am considering purchasing some custom sleeved cables to replace the ones I currently have though.

Like this https://www.amazon.co.uk/Powercool-24-Pin-Female-Extension-Braided/dp/B00I96L7DG/ref=sr_1_1?ie=UTF8&qid=1486222057&sr=8-1&keywords=braided+cable+extension+24+pin

one for 24 pin and another for my GPU
